What would it be like?

Not all of the article is interesting to me. But it makes me wonder, why I never thought of what is the smell on the moon like?
In many mythologies, it is believed that people are made from earth and return to the dust. If there were people on Moon or Mars, they would be made of dust from that place. From the news of it, they would be pretty corrosive people to come in contact with. Has someone warned Carl Sagan about this?
The moon's a desert and if it has any plants, I might know what the summer evening smells like- Arizona summer evening.
